Lyophilization or Freeze Drying technology is the latest in food preservation which makes perishable food, shelf stable without the need for refrigeration. It also removes water from the food (66% of meat is water, more than 80% of most veges. are water) while retaining almost all nutrients and micros. The dry weight could be as low as 1/4rd of the net weight! No kidding! All you need is to add back water to re-constitute.
